Review of the tribe Mutillini (Hymenoptera: Mutillidae) from the Oriental Region.

The species in the tribe Mutillini (Mutillidae: Mutillinae) sensu Waldren et al. (2022, in press) of the Oriental region are reviewed. Fourteen species in the genera Kurzenkotilla Lelej, 2005, Mutilla Linnaeus, 1758, Standfussidia Lelej, 2005, and Storozhenkotilla Lelej, 2005 are keyed, reviewed, and illustrated.

A haemocyte tropism for an arbovirus.

Horizontally transmitted mosquito-borne viruses enter the midgut with a blood meal then disseminate to infect the salivary glands. En route to the salivary glands, these viruses encounter the plasma (haemolymph) and blood cells (haemocytes). Haemocytes respond to a variety of micro-organisms, but their role in virus replication and dissemination has not been described.

Fox squirrels (Sciurus niger) develop West Nile virus viremias sufficient for infecting select mosquito species.

The West Nile virus (WNV) viremia and shedding profiles of 11 adult fox squirrels (Sciurus niger) infected by needle inoculation or mosquito bite were characterized. Daily mean titers (95% confidence intervals) for all squirrels on days 1 through 6 postexposure (p.e.
